clockwise (in the direction of the arrow) increases the tension and
counterclockwise decreases it.
If the tension is adjusted to tight, a creaking sound may be heard
during stage travel, and the stage stopping accuracy may be
imperiled.
} After long hours of use, the stage guide may be deviated and the stage
travel range may be decreased.
However, this is not malfunction and can be corrected easily as described
below.
[Treatment]
Horizontal direction: Hold the specimen holder and move the stage guide
to the left and right so that it hits the stoppers.
Vertical direction:
Hold the upper stage and move it to the front and rear
so that it hits the stoppers.
Stage Feed Knob Rubber Caps (Optional)
} When the X- and Y-axis knobs are fitted with the rubber caps, the knobs
can be adjusted without slipping and fine adjustment is possible by
holding the knobs with a very light force. The knob rubber caps also
reduce fatigue after long hours of operation.
The U-SHGT thick type (thickness 5 mm) and U-SHG thin type (thickness
2 mm) knob rubbers are available.
To attach the knob rubbers:
First fit the larger knob rubber to the Y-axis (upper) knob from below it,
then fit the smaller knob rubber to the X-axis (lower) knob from below it.
